Immunomodulatory inhibition of osteoclastogenesis by a marine microalgal ethano...
Carletti, Alessio; Pes, Katia; Tarasco, Marco; Rosa, Joana; Poudel, Sunil; Pereira, Hugo; Louro, Bruno; Cancela, M. Leonor; Laizé, VincentBackground: Targeting immune pathways to prevent bone loss represents a promising, yet underexplored therapeutic strategy. Methods: An ethanol-soluble fraction derived from the freeze-dried biomass of the marine microalga Skeletonema costatum (SKLT) was tested for its ability to modulate immune responses and inhibit osteoclastogenesis. Its effects were evaluated in a zebrafish model of bone regeneration, a meda...
First release of the European marine omics biodiversity observation network (EM...
Pavloudi, Christina; Santi, Ioulia; Azua, Iñigo; Baña, Zuriñe; Bastianini, Mauro; Belser, Caroline; Bilbao, Jone; Bitz-Thorsen, Julie; Broudin, CarolineThe European Marine Omics Biodiversity Observation Network (EMO BON) is an initiative of the European Marine Biological Resource Centre (EMBRC) to establish a persistent genomic observatory amongst designated European coastal marine sites, sharing the same protocols for sampling and data curation. Environmental samples are collected from the water column and, at some sites, soft sediments and hard substrates (A...
Building a Portuguese coalition for biodiversity genomics
Marques, João P.; Alves, Paulo C.; Amorim, Isabel R.; Lopes, Ricardo J.; Moura, Monica; Myers, Eugene; Sim-sim, Manuela; Sousa-Santos, CarlaThe diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes...

European marine omics biodiversity observation network: a strategic outline for...
Santi, Ioulia; Beluche, Odette; Beraud, Mélanie; Buttigieg, Pier Luigi; Casotti, Raffaella; Cox, Cymon J.; Cunliffe, Michael; Davies, NeilMarine ecosystems, ranging from coastal seas and wetlands to the open ocean, accommodate a wealth of biological diversity from small microorganisms to large mammals. This biodiversity and its associated ecosystem function occurs across complex spatial and temporal scales and is not yet fully understood. Given the wide range of external pressures on the marine environment, this knowledge is crucial for enabling ...
Transcriptomic down-regulation of immune system components in barrier and hemat...
Sousa, Carmen; Power, Deborah; Guerreiro, Pedro M; Louro, Bruno; Chen, Liangbiao; Canario, AdelinoThe environmental conditions and isolation in the Antarctic have driven the evolution of a unique biodiversity at a macro to microorganism scale. Here, we investigated the possible adaptation of the teleost Notothenia coriiceps immune system to the cold environment and unique microbial community of the Southern Ocean. The fish immune system was stimulated through an intraperitoneal injection of lipopolysacchari...
Transcriptomics reveals that the caudal neurosecretory system in the olive flou...
Yuan, Mingzhe; Zhang, Xueshu; Louro, Bruno; Li, Xiaoxue; Canario, Adelino; Lu, WeiqunIn farmed animals, personalities have demonstrated links to performance traits, health and welfare, disease susceptibility, and to coping with environmental stress. The teleost caudal neurosecretory system (CNSS) of the posterior spinal cord is involved in the regulation of the osmoregulatory and stress responses and can directly sense a hypothermal challenge via a transient receptor potential ion channel. Here...
A new subfamily of ionotropic glutamate receptors unique to the echinoderms wit...
Sania, Rubaiyat E.; Cardoso, João; Louro, Bruno; Marquet, Nathalie; Canario, AdelinoChemosensation is a critical signalling process in animals and especially important in sea cucumbers, a group of ecologically and economically important marine echinoderms (class Holothuroidea), which lack audio and visual organs and rely on chemical sensing for survival, feeding and reproduction. The ionotropic receptors are a recently identified family of chemosensory receptors in insects and other protostome...
Holothurians have a reduced GPCR and odorant receptor-like repertoire compared ...
Marquet, Nathalie; Cardoso, João CR; Louro, Bruno; Fernandes, Stefan; Silva, Sandra; Canario, AdelinoSea cucumbers lack vision and rely on chemical sensing to reproduce and survive. However, how they recognize and respond to environmental cues remains unknown. Possible candidates are the odorant receptors (ORs), a diverse family of G protein-coupled receptors (GPCRs) involved in olfaction. The present study aimed at characterizing the chemosensory GPCRs in sea cucumbers. At least 246 distinct GPCRs, of which c...
